The radial spoke is a multi-unit protein structure found in the axonemes of eukaryotic cilia and flagella. Although experiments have determined the importance of the radial spoke in the proper function of these organelles, its structure and mode of action remain poorly understood.
... The radial spoke is known to play a role in the mechanical movement of the flagellum/cilium ... For example, mutant organisms lacking properly functioning radial spokes have flagella and cilia that are immotile ... Radial spokes also influence the cilium "waveform" that is, the exact bending pattern the cilium repeats ...
Famous quotes containing the word spoke:
“Then the well spoke to me.
It said: Abundance is scooped from abundance,
yet abundance remains.
Then I knew.”
